WP 301 Redirects is a premium WordPress plugin from WebFactory Ltd, the Zagreb-based company that also makes WP Reset. It manages 301 redirects, watches traffic that lands on 404 pages, and can send visitors who mistype a URL to the page with the most similar address, with a setting for how sensitive that matching is. It is aimed at site owners, marketers, developers, and web design agencies.
Beyond manual and automatic redirect rules (wildcards are supported), it includes a Link Scanner that checks every page for broken links and outbound links to sites with a poor reputation or malware, using Google Safe Browsing. Redirects can also shorten and tidy affiliate links. A central dashboard shows redirect and 404 logs and stats for all your sites, such as where visitors come from and which browser they use, lets you run remote actions without logging in to each site, and exports branded PDF reports for clients. The plugin can be white-labeled with your own name, logo, and contact details, and supports email reports for 404s and redirects.
The AppSumo deal is a single one-time plan. License Tier 1 ($49, listed at $158) covers 20 sites and 5 full site scans per month, with white labeling, the license and site manager (remote dashboard), remote site control, and remote site stats. It maps to the Team Plan, there are no codes to stack, and you cannot move between license tiers.
